Q ,Application Bled June 18,

To all whom t may concern:

Be it known that we, ARTHUR R. MEYER and ELMER A. REED,v citizens of the United States, and residents of the city of Chicago,

in the county of Cook and State of Illinois,

have invented certain new and useful Im- -provements in a Loose-Leaf Binder; and we do hereby declare that the followingis a full, clear, and exact description of the same, reference being had to the Aaccompanying drawings, and to the numerals Vof reference marked thereon, which form a part of this specification. M

' This invention relates to loose leaf binders in which leaves can be readily inserted and removed and iny which the leaves are locked by shitable leaf-holding means as disclosed in'l our co-pending application, Serial No.

478,488, iiled 4June 18, 1921, of which the devices illustrated in this application are improvements. 'In said co-pending application, the invention is directed broadly to shiftable leaf-holding means that cooperate with slots in the loose leaves, producing a binder that is'adapted for either pen and ink or mechanical bookkeeping, while the 'presentapplication relates more speciiically to novel means for actuatingsaid leaf-holding means.

It is therefore an object of` this invention to provide cam actuating mechanisms yfor shifting the movable leaf-holding means or posts that provide an efficient and easy mode of operation. l With this and other objects in view which will beV become more apparent in the following4 description and disclosures in the drawing, this invention comprises the n ovel features of construction and combinations 40 hereinafter described and pointed out in the appended' claims.

As shown on the-drawings: 70

Thebind'er to which our invention is applied comprises lthe side walls 1 having the iianges 2 which slidingly rest upon 'the base or' ack 3 of the binder having the ends bent or crimped over the side 4flanges 2. The 75 side walls 1 are adapted to be drawn together or spread further apart by means of a screw element 4 having rv'ersel threaded sections upon which the shiftab e nuts or elements 5 are mounted, which are connected 'bly means of links 6 to the side walls 1, as

wn ixnFigures 1 and 5.

In referring to Fi ures 1 to 4, the leafengaging posts l7 an 8 'are supported at a suitable height from the base or back 3 by slidable plate members 9 and 9a which are slidably mounted `upon the inner sides of the side walls 1 .by means of headed studs or rivets 10, the Shanks of which operate .in slotsl 11 in said side walls.v The slots are of such a length as to allow the posts to'move sufliciently for locking andunlocki ng -purses. In the present instance,there are twoJ slidable plate members 'on each side wall,

with.' downwardly' pro]ecting spaced cam lugs 12 defining c am grooves for shift, ing purposes. Each plate member 9a and he l member 9` directly opposite 1 constitutes a .pair which supports one or more pairs -o leaf-holding posts 7 land 8, which constrains said pair to move as a unit thus creating two pairs of shiftable leafholdin devices that mve `as separatennits.

This invention relates more directly to novel cam actuatingmeans for shifting said`i units. In the 1form illustratedin Figures 1 to 4, the' slidable plate-members `9a which-are ool Q and the side walls 1 upon pivot pins 14 extending through said side walls. 'llhe levers or devices 13 havetheir inner end portions .inlined or at an angle, the pivots 14 passing through the inclined ort'ions and the ends of the inclined or ang ed portions are provided with cam lugs or projections 15 operatively fitting in said cam grooves. 'llhe ends of the cam levers 13 project beyond the ends of the binder and by grasping these devices and rotating themen their pivots intoupri ht positions, as indicated 1n dotted lines in igure 2, the shiftable units will be moved outwardly into locklng position, in which position the posts 7 and 8 will have moved into the outer portions of the mushroom slots of the loose leaves. IWhen it is desiredto insert or remove a leaf, the cam devices 13 are again rotated to Jull line position, in which position the leaf-holding posts are directly opposite .the entrance neck off the slots. During the operation of the 'levers 13, the cam lugs operate in the cam grooves formed b the lugs 12, which ooves are of Such a epth as to allow the ugs 15 to travel inthe arc of a circle with pivots 14 as centers. .'lhe cam! lugsl 15 accordingly slide in the said grooves and exert a cammg action against the walls thereof to shift said plates.

llllowever, instead of using twhf separate levers, rotatable disks may be substituted therefor in which cam roove'sfiznay be cut and the cam lugs plac on the inner ends oil said slidable plates, as illustrated in Figures 5 to' 10. ln this form, in which two.

rotatable disks or devices are used,the slidable plates 17, which are supported similarly to the -plates 9, are provided with downwardly extending lugs 18 at their inner ends and having projections or cam lugs 19 which engage in cam'slots -20. and 21 formed in rotatable disks or devices 22 mounted upon an. adjustable shaft 24 extending through bothl side walls of tha hinder., 'lhe adjustable shaft' 24 consists 'of two telescopic sections of polygonal vcross section `aording relativesliding movement, but constrained to rotate as a unit. 'llhe said shaft 24 is supported in bearings in the side walls land just beyond the outer surface of said side walls, the said disks or devices 22are ait- -fllixed to said shaft to lrotate therewith. At one side theshaitt. 24 projects beyond 4.erating knob or handle 25. lThe lugs said plates 17 the protecting sheath 26 to?v receive 'an op- .19 on' roject through longitudinal slots 27 forme the said grooves 2,0 and 21 which are of such ya, contour that the lugs 19 lwill be' shifted yfrom. one endto the other in said slots as in the side walls 1 and into geraete the disks 22 are rotated to shift the plates 17 and the leaf-holding posts carried thereby. ll necessary,l the inner edges of the lugs 18 may be cut out (asshown in Figures 6 and 9) to fit around the' shaft 24 when said plates are shifted together. While ll have illustrated two cam disks, it is apparent that one would answer the purpose, since the two pairs of plates 17 which supportsthe leaf holding posts are constrained totraved as units. 'lhe second disk or device will, however, edect a better balance oit the force exerted.

lt is obvious that by rotating the knob ttl which they shift for locking and unlocking loose leaves having appropriate slots coacting with the posts carried by said slidable plates.

We are aware that numerous details of construction may be varied through a wide range without departing from tlm prinlll@ ciples of this invention, and we therefore do not purpose limiting the patent granted otherwise than necessitated by the prior art.

We claim as our invention:

` f1. lln a leose'leaf binder, a plurality of" l "shiftable leaf-holding units, cam lugs projecting from-said units, and a rotatable cam disk having cam grooves engagingv said lugs y an'd rotatable for shifting said units.

2. ln a loose leaf binder, a vpluralit of pairs of shittable post-supporting mem ers, each member having cam lugs projecting ed in said binder, two cam disks havin cam grooves'mounted on said shaft, one adjacent each side off' the binder, for engaging said from its inner end, a rotatable shaft mountllt cam lugs', whereby said members may be -v shifted by the rotation ol said shaft."

3. lln a loose leaf binder, a leaf-holding device shiftable as a yunit comprising a pair 1 of slidably mountedl plate members, leafholding posts carried by said members, and a rotatable device pivoted adjacent said leafholding device, one of said devices having. 'fa cam groove and the other having a lug entering said groove whereby oscillation of said rotatable device will shift said leafholding device. v

4. ln a loose leaf binder, a longitudinally shiftable leaf-holding unit comprising'a air of slidably supported and parallel p ate tra' members, leaf-holding posts supported by said plate members and slidable therewith, and means for shifting said leaf-holding unit comprising an oscillatable member pivoted adjacent thereto and having a pin and slot connection with said unit.

5. In a loose leaf binder, a longitudinally shiftable leaf-holding unit comprising a pair of leaf-holding posts, and means for shifting 10 said unit comprising a rotatable cam device having a cam-like engagement with sald umt.
